Customization Guides & Code Snippets

◆Translating Calendar Weeks into Percentage Offsets

Calculate task start and width coordinates proportionally against total project duration (e.g. 12 weeks) using ((startWeek - 1) / totalWeeks) * 100.

const leftPct = ((task.startWeek - 1) / 12) * 100;
const widthPct = (task.duration / 12) * 100;

◆Task Progress Completion Overlays

Nest an absolute-positioned progress child div with semi-transparent white fill inside the main task bar to visualize sprint velocity.

TIP 2Always show a time period selector (Today / 7d / 30d / 90d)
TIP 3Load charts progressively — KPI cards first, then charts
TIP 4Use skeleton loaders while data is fetching to prevent layout shift
TIP 5Keep color usage minimal — pick 2-3 accent colors maximum

Frequently Asked Questions

Can you build a Gantt chart in React (gantt chart react)?

Yes, you can build high-performance, lightweight Gantt charts in React without heavy legacy libraries by translating task start dates and durations into percentage offsets along a CSS or SVG grid timeline.

How do you show task progress in a React Gantt chart?

Nest an inner progress fill element with a translucent white background inside each task bar, setting its width to the completion percentage (e.g. style={{ width: `${task.progress}%` }}).

When should you use a Gantt chart vs a timeline chart?

A timeline chart displays discrete milestone points along a linear chronological axis. A Gantt chart displays both start dates and ongoing duration spans, making it essential for tracking overlapping task dependencies and team resource allocations.
